In case you didn't hear (but that seems impossible), Yeezy popped the question to his ladylove on her birthday on Monday, and she said yes!

But Kimye have experienced many milestones together before going through with the $3 million surprise proposal—like welcoming their daughter North West into the world, for example.

So as we continue to congratulate the lovebirds and prepare for what's to come, let's reminisce on the couple's road to engagement.

April 2012: After playing coy about their relationship for nearly a month, Kimye made it clear that they were an item after proudly showing off their new relationship for all the world (or at least the world's paparazzi) to see by holding hands while leaving the opening celebrations of Scott Disick's new restaurant in New York.

May 2012: Once the cat was out of the bag, the pair continued to travel the world together and didn't shy from displaying some PDA. Kim and Kanye fogged up camera lenses up and down the French Riviera while they celebrated the premiere of Kanye's new film Cruel Summer at the Cannes Film Festival.

August 2012: The couple became the subject of marriage rumors quickly, with Kris Jennertelling E! News that the family "adored" Kanye and "we think they make an amazing couple. We just want them to be happy."

December 2012: The couple continued to go strong for months, traveling the world and showing off their budding romance, and on one special night, Kanye announced that the pair were adding another little one into the mix. On Dec. 30, 2012, during his concert in Atlantic City, Kanye shared the thrilling news that he and Kim were expecting their first child.

January 2013: With a baby on the way, the twosome decided to purchase a home together, but not just any home. Kimye splurged on an $11 million mansion in Bel-Air, Calif.

February 2013: Kim graced the April cover of Cosmopolitan and talked about her pregnancy and relationship with Kanye. "I've always said that I wanted kids, but I don't think I ever would have been ready until now," Kim said of her baby-on-the-way. "Sometimes you're just not ready. A person could have it all, and you're not ready for it all. But this is where I probably always should have been," she added, referencing her relationship with her rapper beau.

The E! star added, "[Marriage] is something I know that we both want in our future, but I don't have this sense of urgency about it," she revealed. "I have this best friend who understands me and helps me through all my tough experiences, and vice versa, you know? It just feels like this is it for me."

The parents-to-be also caused a bit of controversy after posing nude for French magazine L'Officiel Hommes, in a number of very steamy shots, including the cover where the sexy pair are wrapped up in each other's arms in an intimate embrace.

June 2013: After countless months of court hearings, Kim Kardashian and Kris Humphries' divorce was officially final. Kim and Kanye also revealed that they were expecting a girl. "I'm so excited we're having a girl," the pregnant star said. "Who doesn't want a girl? They're the best and I know that's really what Kanye has always wanted. He wanted a little girl."

Engagement rumors quickly began swirling, but sources confirmed that a proposal didn't happen...yet. "I can't imagine them not getting married. That's in their future!"

August 2013: Kim and Kanye stepped out of the spotlight for a bit after welcoming their daughter into the world, but nearly a month after Nori's birth, Kim resurfaced toting her baby girl in her car seat while making their way in to a doctor's office.

Then, during an appearance on The Kris Jenner Show, 'Ye unveiled the first photo of North, and just like everyone said, she's beautiful.

"I'm being with this person because, you know, I love this person," he told Kris of Kim during the show. "And she's worth it to me...She's my joy. And she brought my new joy into the world."

And Kim didn't just welcome Nori into Kanye's life—she introduced him to the whole Kardashian-Jenner clan. "After I lost my mother [Donda West, in 2007] there was times I felt like I would put my life at risk. I felt like sometimes I didn't have something to live for, and now I have two really special people to live for," the rapper says, looking to Kris, "A whole family to live for. A whole world to live for."

September 2013: For their first time since becoming parents, Kim and Kanye were able to take a little trip together, just the two of them. The pair went to enjoy the designs from Paris Fashion Week while keeping their baby girl close to heart by each strutting matching "Nori" necklaces.

Oct. 21, 2013: Along with celebrating her 33rd birthday, Kim was surprised with a very romantic proposal from Kanye. The rapper took the E! star to the AT&T Park stadium in San Francisco and got down on one knee. Yeezy presented Kardashian with a flawless 15-carat Lorraine Schwartz diamond ring while a 50-piece orchestra played in the background and a jumbo screen flashed "PLEEEASE MARRY MEEE!!!"

Once Kim said yes, a number of her friends and family members ran out to the field from the dugout to surprise her.
